The Equipment must not be installed with the horn facing

t

A

upwards of horizontal.
To maintain the ingress protection rating and mode of

protection, the cable entries must be fitted with suitably
rated cable entry and/or blanking devices during installation.
If conduit is used for installation, seal conduit within 18
inches from the enclosure.

If entries are fitted with adaptors they must be suitably rated
for the application. Fitting of blanking elements into
adaptors is not permitted.

If a high IP (Ingress Protection) rating is required then a
suitable sealing washer or O-ring must be fitted under any
cable gland or blanking d ev i c e w ith metric thr e ad s .

Only the explosionpr oof cover is to be used f or access to
the enclosure for installation, service and maintenance.

Connections are to be made into the terminal blocks using
solid or stranded wire, sizes 0.5–2.5mm

2

/ AWG 20–12.
Wire insulation needs to be stripped 6–7mm. Wires may be
fitted securely with crimped ferrules. Terminal screws need
to be tightened down with a tightening torque of 0.4 Nm / 3.5
Lb-in.

Earthing connections should be made to the Internal Earth
terminal in the explosionproof chamber or the external
earth stud.

Check that the O-ring seal is in pla c e b ef o re re p la c i ng the
explosionproof cover.

4.2 Mounting

Pub. 42004-502A

d. Replace the explosionproof cover of the loudspeaker,

taking care not to damage the explosionproof threa ds and
checking that the O-ring seal is in place. Tighten the cover
fully.

4.4 Hornless Variants

The 13310-3xx Loudspeaker is also availa ble as a varian t
with no horn fitted in the factory. The Horn threaded nose
portion has a fitment thread of 1-3/8” – 18 UNF (to BS1580
or ANSI B1.1). The customer is responsible for sourcing
and correctly fitting a suitable horn that meets all of the
relevant safety requirements.

5)

Access to the Explosionproof Enclosure

In order to connect the electrical supply cables to the
loudspeaker, it is necessary to remove the explosionproof
cover to gain access to the explosionproof chamber. This
can be achieved by unscrewing the explosionproof cover,
taking extreme care not to damage the explosionproo f
threads in the process.

13310-3xx Loudspeakers should only be installed b y trained
competent personnel.

The Loudspeakers may be secured to any flat surface using
the three 7mm fixing holes. The enclosure provides IP66
protection and is suitable for indoor and outdoor use
providing it is positioned so that water cannot collect in the
horn, and the cable entry is sealed.

4.3 Installat io n Pr o c ed ure
a. Secure the Loudspeaker to a flat surface via the three

7mm fixing holes in the mounting bracket.

b. Remove the e xplosionproof c over o f the l oudspeaker by

terminals as shown in Section 6 / Figure 3 (70V Line In)
or Section 7 / Fi gure 4 (Low Imp edance) of this manual.
The power supply terminals on th e low impedance units
are duplicated so that units may be connected in parallel.
An end- of- line m onitor ing resi stor may be fitted to ei ther

See Section 5 of this manual for access to the explosionproof
enclosure. The 70V Line loudsp eakers are fitted with a five­way terminal block. Terminal A is common and one of the
other terminals B, C, D or E should be selected depending
on what output level is required. (See table below.)

Terminals Watts

A - B 25W
A - C 12.5W
A - D 6W
A - E 2W

For 8

-ohm and 16-ohm models a single conductor with a
cross sectional area of up to 2.5mm² / ~13 AWG can be
connected to each terminal. The 70V transformer model is
supplied with two (2) sets of terminals (in and out), a single
conductor with a cross sectional area of up to 2.5mm² / ~13
AWG can be connected to each terminal. If more than one
wire is fitted into a terminal, a ferrule should be used to
secure the wires. When connecting wires to the terminals,
great care should be taken to dress the wire so that when the
cover is inserted into the chamber the wires do not exert
excess pressure on the terminal blocks.

9)

End-of- Line DC Mo nitoring

On 13310-3xx Loudspeakers, DC line monitoring can be used
if required. Both the 70V Line units and the Low Impedance
units have blocking capacitors fitted. It should be noted that
each loudspeaker has a 1M ohm bleed resistor connected
across the blocking capacitor and this should be taken into
account when selecting the value of the end-of-line monitoring
resistance.

The end-of-line monitoring resistor can be connected across
the terminals on the end- of-line unit .

On 70V line units, the end- of- line resistor used must have
a minim um res ist an ce v alu e of 4k 7 o hms and a min i mum
wattage of 2.5 watts.

On low impedance unit s, the e nd- of- li ne re sis tor use d must
have a mini mum res ista nce valu e of 2k ohms an d a minim um
wattage of 0.5 watts or a minimum resistance value of 500
ohms and a minimum wattage of 2 watts. On the low
impedance units, care must be taken with the polarity of the
monitoring voltage. If an end-of-line resistor is fitted to a unit,
the links on the printed circuit boards of all loudspeakers in the
line must be cut for the dc blocking capacitors to be in circuit in
order to dc monitor the line. (See Figure 4.)

10)

Maintenance, Repair and Overhaul

Maintenance, repair and overhaul of the equipment should
only be carried out by suitably qualified personnel in
accordance with the current relevant standards and
regulations.

Units must not be opened while an explosive atmosphere
is present.

If opening the un it during maint enance ope rations, a clean
environment must be maintained and any dust layer
removed prior to opening the unit.

The threaded flame path joints are not intended to be repaired.

2

/ 18 AWG in size.

The 8- ohm and 16- ohm low impedance models have
dual input terminals on the PCB assembly for input and
output wiring. A cable of up to 2 .5mm² can be
connected to each terminal. If DC line monitoring is used, cut
the link on the board. (See Figure 4.)

8)

Earthing

The unit has both a primary internal and secondary
external earth fixing point.

Internal earth connections should be made to the internal
Earth terminal. See Figure 3 and Fi gu r e 4. It s houl d be fit ted
to the in te rnal earth point using a ring cr imp terminal to
secure the earth con du c t or.

In addition , external ea rth connecti ons can b e made to t he
M5 earth st ud (s ee Figure 2 ), usi ng a ring crimp t er mi nal to
secure the earth conductor to the earth stud. The external
earth crimp ring should be located between the two M5
plain washers provided and securely locked down with the
M5 spring washer and M5 nut.



The earth conductor should be at least equal in size and
